HOG-HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 272,422, dated February 20, 1883.

' Application nien July 21,1ss2. (No model.)

To allwhom 'it may concern Beit known that I, Gnoeen B. FLANIGAN, a citizen of the United States, residing at Kansas City, in the county ot Jackson and State of Missouri, have invented an Improved Hog- Hoisting Apparatus, of which the followingis a specification.

The'object-of my invention is to provide a machine by means of which hogs can be readily handlcd,elevated,andsuspended'ou aninclined rail for slaughter, &c., with ease and rapidity. In the accompanyingdrawingsI have shown my organization of apparatus iu connection with a building representing the hog-killing department of a packing-house. 0f course, however, this arrangement will be varied in many ways to suit the special convenience of each establishment without varying the general operation or structure of the apparatus.

Figure 1 is an interior sectional view of a packing establishment having my apparatus arranged therein. Fig. 2 is a detailed View of the hog-hoisting drum and rope-guide, and Figs. 3 and 4. are detail sectional views of the clutch devices.

The main shaft A is mounted in suitable bearings in a frame-work, B, in the lowerrooin ofthe building. This shaft carries a grooved drum, C, on which is wound the hog-lifting rope D, and also with anotherdrum,E, on which is wound the rope F, which lifts the weight G, that servesto return the drums and shaft to their normal position after the lifting operation, as willbe presently described. The shaft A is driven from the power-driven shaft A. A belt, A2, passes over the pulley c on the shaft A and over the pulley a on the end of a counter-shaft, X, mounted in'suitable bearings in the frame B.

The shaftXcarriesasmallfriction-pulley X', with which the larger friction-pulley, X2, on the shaft A is thrown into engagement in the following manner: The outer end, in the drawings, of the shaft A has its bearing in an eccentric, x, which is carried in thecollar or open end of the lever-arm 71.3, which latter turns in the strap or bearing x. By turning the eccentric in one direction or the other the shaft A may be shifted slightly laterally to throw the pulleys X' and X2 into or out of contact. This arrangementis common and forms no part which carries at its end a small weight,

of my invention. The eccentric-lever arm h3 is operated by a rope, I, which passes over suitable pulleys into the upper room of the building, andis connected with a lever, I', within reach ofthe workman in charge of the apparatus, asis clearly illustrated in Fig. 1.

The drum O is reduced, say, about one-sixth of its diameter at the part c, so that at lirst, when the hog-lifting rope is being wound upon the large portion of the drum, the lift will be comparatively rapid, and will then be promptly slowed up when the rope reaches the reduced portion of the drum and the hog has been elevatedto the desired point, as will be hereinafter described. y

In order to accurately lay the hog-lifting rope into the groove C on the drum U, I eniploy a traveling guide, K, through an eye, 7c, in which the hog-lifting rope passes. This guide is provided with wheels 7c', which travel upon suitable rails, and is caused to traverse back and forth by a cam-rib, l, ou the face of the wheel L, which works in a rack on the upper face of the rope-guide. The parts are so pro- -portioned and the movements of the rope-guide so timed to the rotation of the drum C that the eye k will move along the drum at the proper speed to accurately guide the rope into the groove thereon. The groove C runs over the edge of the large portion of the drum down t0 rthe smaller part, as seen at c', and leads the rope comparatively abruptly, yet accurately, onto the small part. The hog-lifting rope D passes from the lower room over suitable pulleys to the upper floor, and is provided with a hook at its end. A shorter rope, d, is connected with the hog-lifting rope in the upper room, passes over a pulley, d', and carries a weight, d2, at its end. The weight-rope fEl,

7 passesovera pulley, f, which is shown as placed in the wall of the building, but of course may be located wherever convenient. The 'rope passes through the large weight G, which works on upright guidesg, and whichis limited in its descent by the shoulders g on the uprights. When asnitablelength oftheropeF has been wound upon the drum E the small weight j" will come against the bot-tom of the weight G and the latter weight will also belifted. The purpose of this arrangement is that-when a r oo hog has been lifted and the clutch released the weight G will act promptly with sufficient force to return the drums to their normal position, ready for the next lift. The direct strain of the weight, however, will cease when it strikes the shoulders g g', and the smaller weight j" will be sufficient to take up the slack of the rope and keep it taut. The drumsand the various partsof the apparatus are thus returned to normal position willi an easy movementand without any jar.

The operation of the apparatus is asfollows: The workman in the hog-pen having hooked a hog by theleg and connected the hook with the lifting-rope, the workman on the balcony operates the lever I and throws the machineinto operation. rlhe hog` is lifted very rapidly while the rope D is beine; wound upon the large portion of the drum C. and then, justas the. hotr is reaching' the rail M, the rope cornes upon the small portion of the drum and the movement is slower. The attendant on the balcony catches the hooks on the shackle o, which is secured to the hogls leg,` over the rail M, releases the rope D from' the shackle o, and then throws the clutch out of `aear. The weight Gr, then acting on the drum E with suf- Iicient force, immediately returns the drums to their normal positions, while the weight d2 takes up the slack ofthe rope I) and draws it down into the hog-pen again,ready forthe elevation of another hog'. The hog,r suspended from theinolined rail will slide along;` to slaughter; or the attendant on the balcony may be able to slaughter the hogs as well as perform the other operations above described.

I claim as my invention- 1. The combination, substantially as set forth, of thehog-lifting drum, red uced in diamewilma ter at one end, the hog-lifting rope, its pulleys, the weight-drum, the weight-rope, and the weight.

2. The combination, substantially as set forth, of the hog-lifting drum, reduced in diameterat one end, the hog-lifting rope, its pulleys, the weight-drum, the weight-rope, the small weightattachedthereto,andthclooseweight G.

3. The combination, substantially as set forth, of the grooved hog-lifting drum, the traveling rope-guide, and thccam-wheel which operates the guide.

4. The combination, substantially as set forth, of the shaft A, the groovcd hog-lifting drum, reduced in diameterat one end, thehoglifting rope, the traveling rope-guide, the camwheel for operating it, the weightdrum, the weightrope and weight, and clutch mechanism, for the purpose set forth.

5. The combination ot' the shaft A, the weight-drum carried thereby, the weight-rope, the small weight j", the loose weight G, through which the rope passes, and the guiderods, for the purpose set forth.

6. The combination of the shaft A, the hoglifting drum, the hog-lifting rope, its pulleys, the rope d, its pulley, and the weight d2, substantially as and for the purpose set forth.

7. The lifting-drum, made ofalargerdiameter at one end than at the other, and so arranged that the rope wound thereon will pass directly from one portion to the other, for the purpose set forth.

In testimony whereof I have hereunto subscribed my naine.
